Bipolar outflows are a common aspect of the accretion process that leads to the formation of low-mass stars like the Sun. During the most active accretion stages, jets are observed in the optical forbidden lines of abundant ions of oxygen, sulfur, etc.. These lines indicate that the jets have temperatures in the range from 5,000-10,000 K, hydrogen densities greater than 104 cm-3, and ionization fractions of order 10%. Significant progress has been made recently in understanding the dynamical origin of these outflows in terms of magnetocentrifugal effects. According to the X-wind model, the wind covers 180 deg in both directions and is well collimated along the poles, suggestive of a jet. An analysis is presented of the microscopic processes underlying the observed line emission from the X-wind jet that elucidates the important role of several atomic processes, espcially low-energy charge exchange.
